A GPU based real-time software correlation system for the Murchison Widefield Array prototype
Randall B. Wayth, Lincoln J. Greenhill, Frank H. Briggs
Modern graphics processing units (GPUs) are inexpensive commodity hardware that offer Tflop/s theoretical computing capacity. GPUs are well suited to many compute-intensive tasks i…
The Murchison Widefield Array: Design Overview
Colin J. Lonsdale, Roger J. Cappallo, Miguel F. Morales +45
The Murchison Widefield Array (MWA) is a dipole-based aperture array synthesis telescope designed to operate in the 80-300 MHz frequency range. It is capable of a wide range of sci…
Strong gravitational lensing probes of the particle nature of dark matter
Leonidas A. Moustakas, Kevork Abazajian, Andrew Benson +44
There is a vast menagerie of plausible candidates for the constituents of dark matter, both within and beyond extensions of the Standard Model of particle physics. Each of these ca…
GPUs for data processing in the MWA
S. Ord, L. Greenhill, R. Wayth +4
The MWA is a next-generation radio interferometer under construction in remote Western Australia. The data rate from the correlator makes storing the raw data infeasible, so the da…
